Hi there,
I just went to the ASTYM Web site and don't see anyone in Canada that does the treatment. But, that said...
After ASTYM, it took about 3 months to get complete, pain-free functionality. I had to stretch and keep doing the strengthening exercises, and the pain faded away.
But I noticed a HUGE difference after 3 or 4 treatments. Like, such a difference I was amazed. From there, it slowly got better.
I'm a big fan of ASTYM. I had it done for plantar fasciitis on my feet, too. It really helps with soft-tissue/repetitive stress stuff.
Good luck, and let me know if I can tell you anything else.
